It is located in the neck, deep to the sternocleidomastoid muscle. [ 5 ] The branches of the cervical plexus emerge from the posterior triangle at the nerve point , a point which lies midway on the posterior border of the sternocleidomastoid.
The ansa cervicalis (or ansa hypoglossi in older literature [citation needed]) is a loop formed by muscular branches of the cervical plexus formed by branches of cervical spinal nerves C1-C3. The ansa cervicalis has two roots - a superior root (formed by branch of C1) and an inferior root (formed by union of branches of C2 and C3) - that unite ...
"Erb's point" is also a term used in head and neck surgery to describe the point on the posterior border of the sternocleidomastoid muscle, approximately 2-3cm above the clavicle, overlying the transverse process of the sixth cervical vertebra, [3] where the four superficial branches of the cervical plexus—the greater auricular, lesser ...
Cervical plexus. The cervical plexus is formed by the ventral rami of the upper four cervical nerves and the upper part of fifth cervical ventral ramus. The network of rami is located deep to the sternocleidomastoid within the neck. The cervical plexus innervates muscles of the neck and areas of skin on the head, neck and chest.
Apex: Union of the sternocleidomastoid and the trapezius muscles at the superior nuchal line of the occipital bone. Anteriorly: Posterior border of the sternocleidomastoideus. Posteriorly: Anterior border of the trapezius. Inferiorly: Middle one third of the clavicle. Roof: Investing layer of the deep cervical fascia. Floor: (From superior to ...
The supraclavicular nerve is a cutaneous (sensory) nerve of the cervical plexus that arises from the third and fourth cervical (spinal) nerves. It emerges from beneath the posterior border of the sternocleidomastoid muscle, then split into multiple branches. Together, these innervate the skin over the shoulder.
The anterior scalene muscle (Latin: scalenus anterior), lies deeply at the side of the neck, behind the sternocleidomastoid muscle.It arises from the anterior tubercles of the transverse processes of the third, fourth, fifth, and sixth cervical vertebrae, and descending, almost vertically, is inserted by a narrow, flat tendon into the scalene tubercle on the inner border of the first rib, and ...
The great auricular nerve is a cutaneous (sensory) nerve of the head. It originates from the second and third cervical (spinal) nerves (C2-C3) of the cervical plexus.It provides sensory innervation to the skin over the parotid gland and the mastoid process, parts of the outer ear, and to the parotid gland and its fascia.
